Subject: RE: 'close' to getting opencl working
A better error message for sure. Now, I will dig in deeper. Also, unstable
does run some tests. It simply fails on GPU.
$ ../run/john -test -form=wpapsk-opencl
OpenCL platform 0: Intel(R) OpenCL, 1 device(s).
Device 0: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
OpenCL error (CL_DEVICE_NOT_AVAILABLE) in file (common-opencl.c) at line
(148) - (Error creating context)
It very well may be that I have to do 'something', ot get this working:
config settings, env vars, etc, that I have not done yet.
It did not appear to be that way from the install dox, but they were also
written for an rpm system, and not a debian system, so there very well may
be setup issues.
Jim.

The sample OpenCL program you mentioned merely probed the device, just like
--list=opencl-devices. So maybe you should try some short hello-world opencl
program that actually runs a simple kernel.
I have seen bleeding list devices but not being able to use them, in
bleeding. That was when my GPU driver had stuck (needing a reboot). I think
unstable currently is better in that regard (may emit some useful error
message).
